Production method of multifunctional exterior wall anti-crack putty

Abstract

The production method of the multifunctional exterior wall anti-crack putty provided by the invention is prepared in parts by weight, consisting of 13-17 parts of tap water, 0.18-0.22 parts of cellulose, 9-11 parts of pure acrylic elastic emulsion, and 18-18 parts of silicon acrylic elastic emulsion. 22 parts, 0.2-0.3 parts of defoamer, 1-2 parts of preservative, 0.8-1.2 parts of thickener, 28-32 parts of white cement, 6-9 parts of heavy calcium carbonate, 15-19 parts of quartz powder; Among them, the best preparation: 15 parts of tap water, 0.2 parts of cellulose, 10 parts of pure acrylic elastic emulsion, 20 parts of silicon acrylic elastic emulsion, 0.3 parts of defoamer, 1.5 parts of preservative, 1.0 part of thickener, 30 parts of white cement , 8 parts of heavy calcium carbonate, 17 parts of quartz powder; synthesized in a reactor, put into tap water, cellulose, silicon acrylic elastic emulsion, pure acrylic elastic emulsion, defoamer, preservative, thickener successively, and fully stir for 13- After 17 minutes, add white cement, heavy calcium carbonate, and quartz powder, stir for 40-50 minutes until uniform, wait for 10 minutes, visually observe that it reaches the required consistency, and use it. The particle size of heavy calcium carbonate is 750-800 mesh; the particle size of quartz powder is 260-300 mesh.

Description

technical field [0001] The invention relates to the production of the putty used for the outer wall, especially the effect of suppressing and anti-cracking, especially the optimization of its preparation and production method. Background technique [0002] The anti-cracking effect of ordinary anti-cracking putty sold in the market is 0.13mm. During the construction, it needs to be stirred evenly with an electric mixer before use. Due to the dust generated during the mixing, it is inevitable to pollute the air; especially the rain After being exposed to moisture, the bond strength of the putty will decrease, and it will be easy to weather and fall off, especially at the temperature of -20°C-40°C, the crack resistance and weather resistance will be significantly reduced after repeated use twice. Literature search: ① patent No. 200610160762.3; ② patent No. 200610027993.7; ③ patent No. 200510027045.9; ④ patent No. 200510111344.0; , and also solves quite a few of the above-menti...
